T(x) is the only function up above where the highest degree is a 2, which is what a quadratic function is: a function of degree 2
Let the number be n.
Then 2(7-n) = 4n, or 14 - 2n = 4n, or 14 = 6n. Then n = 7/3 (answer)
A bag has 5 red marbles, 6 blue marbles and 4 black marbles
so total no. of marbles = 5 + 6 + 4 = 15
now probability of picking a black marble = 4/15
after replacement again probability of picking black marble is 4/15
it is given that black marble is picked two times
so probability of picking black marble two times or picking , replacing , and then picking is 4/15*4/15 = 16/225
Answer:
<h2>
FALSE</h2>
Step-by-step explanation:
The formula of an area of a rectangle:

l - length
w - width
The fromula of an area of a triangle:

b - base
h - height
If l = a and w = h, then

<em>The area of the triangle is equal to half the area of the rectangle with the same base and height.</em>
<em>The area of the rectangle is equal to twice the area of the triangle with the same base and height.</em>
